Adrenalectomy--still a must in radical renal surgery?

Abstract

Objective: To investigate the incidence of adrenal involvement and survival in patients with renal cell carcinoma.

Patients and methods: A retrospective, multicentre trial was initiated by the Austrian Association of Urologic Oncology (AUO); between January 1980 and December 1984, 225 patients were eligible for the study. All patients had unilateral renal tumours and nephrectomies were performed either with (group A, 109 patients) or without (group B, 116 patients) adrenalectomy. The two groups were matched for sex, age, laterality and nodal status. The mean follow-up time was 78 months.

Results: The location of the intrarenal tumour had no significant effect on adrenal involvement. By univariate and multivariate analysis (Cox's proportional hazards model) significant differences in outcome were found only for pT stages. The mean survival times of patients in group A were 122.9 months in those with stage pT1/2, 76.6 months with stage pT3 and 75.3 months with stage pT4. In group B, survival times were 109 months in those with stage pT1/2 (not significant) and 111 months in stage pT3 (P = 0.0076). Eight patients had adrenal involvement and died from their tumours after a median of 15.3 months (range 4-63). The slightly longer survival of patients in group B with stage T1/2 tumours and the significantly better survival of patients with stage T3 disease may be attributable to statistical bias, but there was no benefit from adrenalectomy.

Conclusion: The effect of adrenalectomy on the prognosis was at best comparable to that of lymphadenectomy and no curative effect was demonstrated. The removal of a healthy adrenal may be detrimental and cause subsequent problems in those patients requiring hormone replacement.
